Since it preferably decays into two charmed baryons $\\Lambda_c\\bar\\Lambda_c$, it is tempted to conjecture it as a tetraquark. Because the dominant decay portal $Y(4630)\\to \\Lambda_c \\bar\\Lambda_c$ is close to the energy threshold, the final state interactions may be significant and result in other baryonic and/or mesonic final states whose branching fractions are sizable to be measured in the future experiments.
